For the purpose of forcing the projections downwardly to permit the rotation 4of the cover for opening the box7 l provide a key 21 having a shank22 and provided with two iiat projections 23 and I Vprovide thewall through which the' operating part of the key can be projected into the bankY above the arms 16. riheope'ning '24 is' arrangedabove of the member 17V just to the rear fof the projections 14.
